Mueller A, et al. - In the interventional angiography suite, researchers sought to study the authenticity of preinterventional pooled blood volume (PBV)-maps acquired by flat-panel detector CT. For this investigation, they compared the volumes of preinterventional perfusion deficit in flat-panel detector CT-PBV source images with final infarct volume on follow-up multislice-CT after endovascular treatment of 29 consecutive individuals with occlusion of the middle cerebral artery (MCA) or the distal internal carotid artery (ICA). In 26 patients (Thrombolysis in Cerebral Infarction, 2b-3), endovascular treatment was successful. According to findings, CT-PBV flat panel detector is not effective in estimating the final volume of infarction and should not be used in medical decision making to treat acute cerebral artery occlusions in endovascular therapy.
